You don't need to escape the quote character (in fact it is \, not /, unless you were confused with the standard regex delimiters) if the string isn't delimited with the same character.
如果字符串没有用相同的字符分隔，则不需要对引号字符进行转义（实际上它是\，不是/，除非您与标准正则表达式分隔符混淆）。
$page = str_replace("'", '"', $page);

这应该有效：
str_replace("'",'"',$text);

I think you should do replacements with preg_replace();
我认为你应该用preg_replace();做替换；
$str = "'Here 'it' goes'";
echo preg_replace("/'/", '"', $str);

This works. You actually don't need any escaping character.
这有效。你实际上不需要任何转义字符。
$page = str_replace("'", '"', $page);

You only need the start and end /for preg_...()(and other regex) functions. For basic functions such as str_replace, simply use the characters:
你只需要在开始和结束/的preg_...()（和其他正则表达式）功能。对于诸如 之类的基本功能str_replace，只需使用字符：
str_replace("'", '"', $text);
